Since the current documentation does not work, please provide a step-by-step solution on how to push a Video to the Google Drive.

I'm trying to make my Android app to upload a Video format file to my Google Drive account. The whole code:

In order to upload the video to the Dirve, I need to connect to the Drive first. I followed the steps on how to create to use the API ( docs ). Then I followed this example , which should show how to connect to the Google Drive and list the content.

But, before even pressing the "upload" button, I get an error to connect to the Google Drive:

java.io.IOException: unable to create directory: /tokens

On line:

GoogleAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow.Builder(
                HTTP_TRANSPORT, JSON_FACTORY, clientSecrets, SCOPES)
                .setDataStoreFactory(new FileDataStoreFactory(new java.io.File(TOKENS_DIRECTORY_PATH)))
                .setAccessType("offline")
                .build();

Please correct me if I'm wrong, but as I understand, it tries to create the token directory locally and not in the remote - but why does it need it? I just want to be able to push the video I got from the user to the Drive. How can I connect to the Google Drive and push the video to the Drive (if you will take a look into a code, I have the uri of the file, that should be pushed to the Drive).

Answer 1

I fell victim to this as well. Unfortunately, the tutorial you're following is for a "simple Java command line application" (stated on the first sentence of the quickstart example). So you are correct, the issue is that it tries create the token directory in order to store the access token, which you need in order to make requests to the Google Drive API.

If you are ok with using GoogleSignInClient to initiate authentication, I believe this should help. Start at the "The Future: Using GoogleApi" section.

If you want to follow the low-level protocol instead you can follow this doc on OAuth2.0 for mobile.

I hope this helps or, at the very least, saves some time.

Answer 2

This works for me:

1. Implement these libraries in your gradle file(app level)

   implementation 'com.google.android.gms:play-services-auth:19.0.0' implementation 'com.google.http-client:google-http-client-gson:1.26.0' implementation('com.google.api-client:google-api-client-android:1.26.0') { exclude group: 'org.apache.httpcomponents' } implementation('com.google.apis:google-api-services-drive:v3-rev136-1.25.0') { exclude group: 'org.apache.httpcomponents' }

2. In your manifest add these permissions

3. Go to Google Cloud Console and make a new project then go to the Library tab and add Google Drive API in it. Now you have to register your app for OAuthConsent Screen. It is required as When you use OAuth 2.0 for authorization, your app requests authorizations for one or more scopes of access from a Google Account.

4. There will be 2 options on OAuth consent screen page 1) Internal 2) External. I used external as only test users wanted to test the Consent screen so click on external and add scopes whatever you want add test users and your work is complete on the console.

5. Now come to your Android App for handling Google signing activity

Code:

 private static final int REQUEST_CODE_SIGN_IN = 1;

    static GoogleDriveServiceHelper mDriveServiceHelper;

    GoogleSignInClient googleSignInClient;

  /**
     * Starts a sign-in activity using {@link #REQUEST_CODE_SIGN_IN}.
     */
    private void requestSignIn() {
        Log.d(TAG, "Requesting sign-in");

        GoogleSignInOptions signInOptions =
                new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
                        .requestScopes(new Scope(DriveScopes.DRIVE))
                        .requestEmail()
                        .build();
        googleSignInClient = GoogleSignIn.getClient(this, signInOptions);

        // The result of the sign-in Intent is handled in onActivityResult.
        startActivityForResult(googleSignInClient.getSignInIntent(), REQUEST_CODE_SIGN_IN);
    }


    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent resultData) {

        switch (requestCode) {
            case REQUEST_CODE_SIGN_IN:
                if (resultCode == Activity.RESULT_OK && resultData != null) {
                    handleSignInResult(resultData);
                }
                break;

        }

        super.onActivityResult(requestCode, resultCode, resultData);
    }

    /**
     * Handles the {@code result} of a completed sign-in activity initiated from {@link
     * #requestSignIn()}.
     */
    private void handleSignInResult(Intent result) {
        GoogleSignIn.getSignedInAccountFromIntent(result)
                .addOnSuccessListener(googleAccount -> {
                    Log.d(TAG, "Signed in as " + googleAccount.getEmail());

                    // Use the authenticated account to sign in to the Drive service.
                    GoogleAccountCredential credential =
                            GoogleAccountCredential.usingOAuth2(
                                    this, Collections.singleton(DriveScopes.DRIVE));
                    credential.setSelectedAccount(googleAccount.getAccount());
                    Drive googleDriveService =
                            new Drive.Builder(
                                    AndroidHttp.newCompatibleTransport(),
                                    new GsonFactory(),
                                    credential)
                                    .setApplicationName("Whaterver the name is")
                                    .build();

                    // The DriveServiceHelper encapsulates all REST API and functionality.
                    // Its instantiation is required before handling any onClick actions.
                    mDriveServiceHelper = new GoogleDriveServiceHelper(googleDriveService);

                                                   
                    showMessage("Sign-In done...!!");
                 

                })
                .addOnFailureListener(new OnFailureListener() {
                    @Override
                    public void onFailure(@NonNull Exception exception) {
                        Log.e(TAG, "Unable to sign in.", exception);
                        showMessage("Unable to sign in.");
                       
                    }
                });
    }
